Frequently Asked Questions
Can my alternator handle the 30A charging current?
You'll need a minimum 100A alternator for reliable 30A auxiliary charging. The charger draws approximately 35-40A from the primary battery during peak charge, so verify your alternator has sufficient capacity beyond vehicle electrical loads before installation.
How much faster is 30A compared to 15A charging?
Approximately twice as fast for the same battery capacity. A 200Ah lithium auxiliary battery requires about 14-16 hours with 15A charging versus 7-8 hours with 30A, accounting for charge curve tapering and efficiency.
Will 30A charging generate excessive heat in engine rooms?
The 96% efficiency and natural convection cooling manage heat effectively, but 30A charging produces significant thermal output. Ensure adequate ventilation around the charger and avoid mounting in sealed compartments. The over-temperature protection will reduce output if thermal limits are reached.
Does this work with 24V truck electrical systems?
Yes, the 10-36VDC input range covers 24V vehicle electrical systems (typically 27-28V during alternator charging). The charger outputs regulated 12V to charge a 12V auxiliary lithium battery from the 24V primary system.
What do the LED indicators show?
The LED display indicates charging state, though specific colour codes or patterns are not detailed in the supplied documentation. Contact F.A.E. for LED indicator interpretation guide specific to this model.
